In order to have something to talk about, I catalogued a lot of Sketchpad resources in Math Tools. There are a number from Key, but also many from other folks, including myself. I'm teaching two Sketchpad Summer Institutes for Key this summer, and hope to make Math Tools an important part of that work so that the participants become familiar not only with the resources that are available, but also with the community of educators who are busily using such "tools" all the time!
